Abstract: An applicator for tampons has a sleeve for the tampon and for a portion of a reciprocable pusher which can expel the tampon by causing the latter to flex outwardly a set of domed petals at the front end of the sleeve. The sleeve is formed by advancing a strip of degradable material longitudinally, by forming spaced-apart portions of the strip with transversely extending rows of hourglass-shaped webs, by converting the strip into a tubular envelope with a seam extending in parallelism with the axis of the envelope, by severing the envelope across the rows of webs so that the envelope yields a series of tubes each having a circumferentially extending set of petals (halves of webs) at each of its ends, and by cutting each tube midway between its ends to form shorter tubes (sleeves) each of which has a set of petals at one end. The petals are thereupon domed to close the respective ends of the sleeves and the other ends of the sleeves are formed with indentations which center the respective pushers.

Abstract: A method and an apparatus are indicated for the production of a cylindrical packing tube which is open at one end and closed at the other, is made from deformable tear-resistant packing material and is intended, in particular, for tampons used in female hygiene, wherein a portion of the packing material is drawn by suction onto a winding spindle provided with suction apertures and through the rotation of the winding spindle is wrapped around the latter, while the overlapping ends of the portion are joined together to form the packing tube, whose end projecting beyond the winding spindle is closed, whereupon the packing tube is removed from the winding spindle. The method is characterized in that that end of the cylindrical packing tube which projects beyond the winding spindle is held fast and during the rotation of the winding spindle is closed so as to form a twist. The method permits the production of a uniform closure pattern of the packing tube irrespective of the shape of the tampon insertion end.
